a propeller board pin question and a motor controller question

I have a propeller bard for a company called inex it has 2 or 3 pins labeled +v then 2 pin next to it that says +5
now on the not so exact schematic it says v+O and 5+O now i know that second one means + 5volts out what is the +vO stand for ..

not for the motor controller

does anyone have a small 2 motor controller that can be hooked to an external power supply but be controlled forward and backward with speed setting . real cheep if you are felling really good a ( donation ) LOL

Ps. You can drive 2 motors on that IC but both must have same sped at time but not nesessary if it not dirves in same time

IC has 4 InX pins to control direction 2 Enable Pins to control Enable one halv of IC with it You can control Motor 1 else 2 ON
With InX Pins control You Direction.
With V+ Motor driving Pin wiyh variable voltage driving You control speed

i really cant figure out if you are talking about an ic that is on the board or built into the propeller chip it self. I reall dont know much about the propeller chip i have been working with the BOE and the HWB so i am a very serious noobie at this ok

The o of +Vo is the schmatic symbol for the end of the wire. Its saying +V, it connected to the +V at the top of the schematic which is the input voltage after the main switch. So if you power the board from a voltage that can run the motor as well you can use this output.
You dont mention what motor you are trying to control. What can be used to control it depends on what the motor needs - voltage and current.

On L289N You can drive up to 2x2A 46V·up to standart motors else 1 up to 4A 46V·steper motor

looked it up and i had to read the customers review to find out that it can draw a max load of 1.5 amp at 1.5 to 3 volts. I have also read that you can push 9 volts though these things but you have to step done the amps. but i am looking to run some ware between the 1.5 to 3 i really dont think i will need no more than 1 amp per motor.

does this sound like to much power. I want to drive a small robot. I am going to have to figure out some gearing. I am going to have to make this cause i cant afford to buy anything like that. because it turns a max of 5800 rpm under load give or take 12 percent. the robot will weight in at any ware from 3 to 10 pounds it depends what i can afford to deck it out with.

her is a question. i have looked this board over with a 4x magnifying glass and can not fine the l289d chip. I am tired and on my pain med i am not comprehending very well are you saying this board can do what i think you are saying. that it can use an external power source up to 2 amp to drive motors using pwm or somthing like that. if so is this built into the prop chip or is it the big chip just behind the power input plug

ps sorry to be so stupid tonight. my brain is rather fuzzy. I take some pretty heavy meds I see a pain clinic so. sometimes i fight to comprehend things a little harder

To that loads You can use relatively smal transistors.
It is only 1.5Ax3V=4.5W

PM to me..
Al parameters on Yours motors.
I can draw for You one schema with posible control alternatives.
One with Constant speed and one with Variable speed..
You can have it tomorrow

If You have Prop board You must Have 3.3 V+ and 5 V+ on board.
Til one motor that have 3 V specification You can use 3.3 V+ with direct Transistor drive with no speed control else PWM to control speed Votage.
Eles 5 V+ with PWM transistor control with no extra Resistor at alls

Yes I got e-posy from You.
My Hotmail acount is not my ordinary e-post but it is OK.
It is MSN if You have that You can have me in Yours Contacts
